The Northeastern Mata Atlântica freshwater ecoregion (NMAF) includes part of the eastern Brazilian coastal drainages, has high level of fish endemism and great biogeographic significance. A taxonomic inventory of freshwater fishes from 25 drainages of the NMAF ecoregion and a biogeographic analysis using the Parsimony Analysis of Endemicity (PAE) method were carried out. A total of 192 native species was listed. The PAE method was applied to 24 basins and 37 species, resulting in five equally parsimonious area diagrams. The strict consensus diagram indicates the existence of two main groups of basins throughout the NMAF ecoregion. These groups were denominated: North Group and Central-South Group. The Central-South Group shows a basal polytomy composed by two Groups (Central Group and South Group) plus the rio Itapemirim basin. The North Group is composed by eight drainages from the rio Sergipe to the rio Paraguaçu, the Central Group by five drainages from the rio Cachoeira to the rio Jequitinhonha, and the South Group by nine drainages from the rio Buranhém to the rio Doce. Comments about the species distribution and the fish fauna shared with adjacent ecoregions are provided. We also present a comparison of the hypothesis of river relationships proposed herein with published phylogenetic hypotheses that include taxa relevant to this study.

Annotated Checklist

An annotated checklist for the freshwater fishes from Paraná State, Brazil is provided. A total of 440 freshwater fish species are recorded for the state, distributed across five ecoregions: Upper Parana, Lower Parana, and Iguassu, all within the rio Paraná basin, and corresponding to the state’s Inland Slope, and Southeastern Mata Atlantica and Ribeira de Iguape, corresponding to the Atlantic Slope, encompassing minor coastal drainages emptying in the Baía de Paranaguá or in the Baía de Guaratuba, and the rio Ribeira de Iguape basin, respectively. The Upper Parana ecoregion ocuppies the larger in area in the state, and is divided into the following sub-ecoregions: Floodplain, Paranapanema, Piquiri, and Ivaí. Species richness for each ecoregion is as follows: 273 species for the Upper Parana (Paranapanema sub-ecoregion, 217 species; Floodplain sub-ecoregion, 193 species; Piquiri sub-ecoregion, 154 species; Ivaí sub-ecoregion, 132 species), 154 species in the Lower Parana, 127 species in the Iguassu, 68 species in the Southeastern Mata Atlantica, and 50 species in the Ribeira de Iguape. We recorded 42 putatively undescribed species and 117 endemic species from specific ecoregions (except Upper Parana) or sub-ecoregions in the state. Ninety-eight species recorded are non-native from at least one of the state’s ecoregions. Thirty-three species are considered threatened. The ecoregions in the Atlantic Slope share many more species with each other than with ecoregions in the Inland Slope. The Iguassu ecoregion is the only one located in Inland Slope that shares more species with the Atlantic Slope than with the remaining ecoregions from the Inland Slope. The Ivaí sub-ecoregion lacks several species that are common to all other sub-ecoregions of the Upper Parana ecoregion. Comments on the historical development of taxonomic knowledge, biogeography, threats, and conservation strategies for the fish fauna from the Paraná State are provided.

This paper aims to examine the representations of Brazilian children from Joinville Region of biodiversity in the Mata Atlântica. We interviewed 112 girls and 90 boys from a school in the city of Joinville, in the Brazilian state of Santa Catarina. These 6 to 14 year old students from grade 1 to 8 were requested to estimate the abundance of plants, animals and microorganisms in the region, and to name the species they know. Our results show that children are aware of the high level of biodiversity in their region, but they had difficulty in naming native species.

<em>Abstract.</em>—From its headwaters in the Rocky Mountains, the Platte River drains 230,362 km<sup>2</sup> in Colorado, Wyoming, and Nebraska. The Platte River is formed by the confluence of the North Platte and South Platte near the city of North Platte, Nebraska, and receives additional flow from the Loup and Elkhorn rivers that drain the Sand Hills region of Nebraska. Water diversions for mining and irrigation began in the 1840s in Colorado and Wyoming, and irrigation diversions in Nebraska began in the 1850s. Construction of dams for control of river flows commenced on the North Platte River in Wyoming in 1904. Additional dams and diversions in the North Platte, South Platte, and Platte rivers have extensively modified natural flow patterns and caused interruptions of flows. Pollution, from mining, industrial, municipal, and agricultural sources, and introductions of 24 nonnative species have also taken their toll. Fishes of the basin were little studied before changes in land use, pollution, and introduction of exotic species began. The current fish fauna totals approximately 100 species from 20 families. Native species richness declines westward, but some species find refugia in western headwaters streams. Declines in 26 native species has led to their being listing as species of concern by one or more basin states.

O objetivo deste trabalho foi avaliar a diversidade de espécies florestais nativas produzidas nos viveiros do estado do Rio de Janeiro. O levantamento e diagnóstico foram realizados durante os meses de fevereiro, março e abril de 2010, sendo incluídos os viveiros que produziam mudas de espécies florestais da Mata Atlântica. O trabalho de campo consistiu em visitas a 70 viveiros florestais, nos quais foi requerida a lista das espécies produzidas e realizada entrevista com o responsável, sendo preenchido um questionário englobando diversos temas relacionados à produção de mudas. Foram observadas 277 espécies florestais nativas da Mata Atlântica sendo produzidas nos viveiros, que, em média, trabalham com 56 espécies nativas. A diversidade total de espécies florestais da Mata Atlântica produzidas nos viveiros do Estado do Rio de Janeiro é baixa, assim como a diversidade média, já que mais da metade dos viveiros trabalha com uma listagem de 50 ou menos espécies, número insuficiente considerando a diversidade de espécies florestais presentes nas diferentes formações vegetais do estado.Palavras-chave: Mudas florestais; restauração florestal; Mata Atlântica. AbstractAssessment of diversity of native species produced in forest nurseries of Rio de Janeiro State. The objective of this paper was to evaluate the diversity of native species produced by nurseries in the State of Rio de Janeiro. The diagnostic and survey were conducted during the months of February, March and April of the year 2010, the research included all nurseries that produced seedlings of Atlantic Forest species. The fieldwork consisted of visits to the 70 surveyed nurseries, in which a list of the species produced in the nursery was requested and the seedling production manager was interviewed, filling in a questionnaire covering various topics related to seedlings production. We observed 277 forest species native from the Atlantic Forest produced in the nurseries. In average, the nurseries produce 56 different native species. The total diversity of native species produced in the State of Rio de Janeiro is low, as well as the mean diversity, since more than half of the nurseries work with a list of 50 or fewer species, what is insufficient considering the diversity of forest species that occur in the different vegetation types of the state.Keywords: Forest seedlings; forest restoration; Atlantic Forest.

Riverine Systems

Freshwater systems and their associated biodiversity are among the most threatened ecosystems globally. The greatest threats to freshwater fishes are the introduction and spread of non-native species, pollution, habitat degradation and loss, and overexploitation. While many regions across the world contain extensive networks of protected areas, these are largely ineffective for protecting riverine systems and their biodiversity. This is because they were designed with the aim of prioritising conservation of terrestrial biodiversity, with limited or no consideration for aquatic systems. The Cape Fold Ecoregion, located within the Western and Eastern Cape Provinces of South Africa, is home to the highest percentage of threatened freshwater fishes in the country. The region has an extensive protected area network that protects a wide array of ecosystems, but limited information exists on the role of protected areas in conserving the endemic freshwater fish fauna of this region. This study evaluated the value of protected areas for protection of freshwater fishes in the Western Cape Province by setting species conservation targets and then intersecting species distribution data with protected area polygons. Conservation targets were set to protect the minimum viable population required for long-term persistence, with a minimum of 10 subpopulations as a target. This, along with other factors such as population viability and protected area effectiveness was used to determine whether a species was effectively protected by the current protected area network. Species were classified into one of four categories; (1) “well protected,” (2) “moderately protected,” (3) “poorly protected,” and (4) “not protected.” Our results indicate that the majority of native fishes are inadequately protected within the current protected area network in the province. This is mainly a result of the linear nature of riverine ecosystems that exposes them to impacts and threats that emanate from outside of the protected area. These limitations are not unique to the CFE, and our findings have broader implications as they highlight the need for integrating both the riverine and terrestrial ecosystems in the design, expansion and management of protected areas. This will enhance and maximise conservation and protection of riverine systems and their unique biodiversity.

AbstractThe new species Micarea corallothallina is described from Serra da Jibóia, Bahia, NE Brazil. It has a gnarled, coralloid, isidiose thallus and pale botryose apothecia. It was found in the Serra da Jibóia, a mountainous range with a maximum elevation of 800 m on smooth bark of trees. This Mata Atlantica fragment is located in the Santa Terezinha municipality, Bahia, NE Brazil, near the Castro Alves municipality boundary. This area can be considered as a rainforest enclave surrounded by Caatinga, and belongs to a disjunct set of mountains that extend from the southern coast of the state to the North-west and North.

The fish fauna occurring in Brazilian small streams comprises 36 families of teleost freshwater fishes. The systematics and phylogenetic knowledge about this fauna greatly expanded during the last two decades, but is still very heterogeneous. For some taxonomic groups there are taxonomic identification keys and well-documented phylogenetic hypotheses, while other groups are mostly comprised by poorly known species. The increase in the knowledge of Neotropical fish diversity was associated with the significant growth of hypotheses about their evolution and contributed to the understanding of the phylogenetic history of fish comunities and their structure in small streams.

Alguns estudos relatam que propostas de tubetes biodegradáveis não suportavam as condições ambientais nos viveiros ou não favoreciam condições necessárias ao crescimento das mudas, implicando nos parâmetros morfológicos necessários a atingir a qualidade padrão de ir à campo. O objetivo deste estudo foi avaliar os parâmetros morfológicos de mudas nativas da Mata Atlântica em tubetes biodegradáveis em viveiro florestal. Foram injetados tubetes biodegradáveis de polietileno de alta densidade, oxibiodegradante orgânico e micropartículas de casca de arroz. Durante 6 meses os tubetes foram utilizados para a produção de mudas nativas. Após este período, foram analisados: altura (H), diâmetro do colo (DC), massa seca da parte aérea (MSPA), massa seca da raiz (MSR), índice de qualidade de Dickson (IQD) e índice de Robustez (IR). Observou-se que as mudas de aroeira e tamboril não apresentaram diferença estatística para as variáveis estudadas. As mudas de genipapo apresentaram diferença estatística para a MSPA e MSR entre os tipos de tubetes. Portanto, os tubetes biodegradáveis podem ser utilizados para a produção de mudas em viveiro florestal, pois não influenciaram nos parâmetros de crescimento e desenvolvimento de mudas de espécies florestais nativas.

Freshwater Fish Fauna

Hainan Island is located within the Indo-Burma global biodiversity hotspot, however, the freshwater fish fauna on this island is poorly understood. Based on field investigations and literature review, we compiled a list of 154 freshwater fish species (138 native and 16 non-native) belonging to 10 orders, 31 families and 104 genera found on Hainan Island. Of these, 31 species are endemic to China. The native freshwater fish fauna in Hainan Island is affiliated to South China sub-region of the Oriental Region. Current knowledge suggests that overexploitation, water pollution, flow modification, habitat degradation, and non-native species have severely reduced the freshwater fish biodiversity in Hainan Island. To protect freshwater fish biodiversity and fisheries in Hainan Island, some new measures should be adopted and current measures better enforced. This study constitutes an important resource for conservation management of freshwater fishes in Hainan Island.

A high level of freshwater fish endemism in the Balkans Region emphasizes the need for non-native species risk assessments to inform management and control measures, with pre-screening tools, such as the Fish Invasiveness Screening Kit (FISK) providing a useful first step. Applied to 43 non-native and translocated freshwater fishes in four Balkan countries, FISK reliably discriminated between invasive and non-invasive species, with a calibration threshold value of 9.5 distinguishing between species of medium and high risk sensu lato of becoming invasive. Twelve of the 43 species were assessed by scientists from two or more Balkan countries, and the remaining 31 species by a single assessor. Using the 9.5 threshold, three species were classed as low risk, 10 as medium risk, and 30 as high risk, with the latter category comprised of 26 moderately high risk, three high risk, and one very high risk species. Confidence levels in the assessments were relatively constant for all species, indicating concordance amongst assessors.
